How can I stop getting bullied at school?

Try to give them a decisive, bold response. Keep it simple and don't use any fancy words that would make them bully you more for sounding intelligent. It depends on what they say or do, but try something like "Look, I don't really care what you think about me" (keep a casual but ertive tone and also don't try to sound like you're just bullying them back) or roll your eyes or raise an eyebrow if they're whispering about you or if they say something mean, ignore them silently as they say it and then look up and reply "Yes?" like you weren't even listening to what they were saying. You shouldn't become a greater bully or anything, but just ignore a lot of it and be ertive if you have to say something in response. Or if they say something mean directly to you, either continue working on whatever you're doing or look them in the eye and say "That's fantastic" or "That's great" in a sarcastic tone. Show them their words don't affect you, and be strong. :)
